OBJECTIVE To analyze the frequency and severity of subclinical cerebral complications associated with coronary artery bypass grafting (CABG). DESIGN A prospective controlled study using preoperative and postoperative magnetic resonance imaging (MRI) of the brain, quantitative electroencephalography (QEEG), and detailed neuropsychological and neurologic… (More)
The suitability of the cerebrospinal fluid (CSF) in the lumbosacral dural sac as an internal signal-intensity reference was studied on magnetic resonance imaging (MRI) of the lumbar spine using a surface coil and motion artefact suppression technique. A signal-intensity reference is needed when signal is compared between images, studies or subjects.… (More)
PURPOSE To determine the most accurate, safe, and cost-effective imaging protocol for selecting patients for carotid endarterectomy. METHODS The actual costs of carotid angiography, ultrasound, and MR angiography were calculated. The diagnostic accuracy with different confidence levels was assessed for carotid ultrasound and MR angiography in 45 patients.… (More)
PURPOSE To evaluate different carotid stenosis estimation methods with digital subtraction angiography. METHODS We assessed the intraobserver reproducibilty and interobserver variability of visual interpretation and the measurement methods used by the European Carotid Surgery Trial and the North American Symptomatic Carotid Endarterectomy Trial.… (More)
This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Aerosol particles play important roles in regional air quality and global climate change. In this study, we analyzed two-year (2011–2013) of measurements of submicron particles… (More)
This thesis is based on the following original articles, which are referred to in the text by their Roman numerals.aneurysmal thrombus on the interplay between coagulation and inflammation in open and endovascular abdominal aortic aneurysm repair. Submitted.
A patient with cervicocranial fibromuscular dysplasia (FMD) presented with subarachnoid hemorrhage. A ruptured dissecting distal vertebral artery aneurysm required clip ligation of the parent artery; a contralateral dissecting proximal vertebral aneurysm was occluded with detachable coils. Progressive dissecting, extracranial aneurysms of the internal… (More)
A patient with bilateral chronic brachialgia was cineradiographically shown to have hypomobile first ribs bilaterally. This finding can be elicited by the Expiration-Inspiration (E-I) test, in which the patient is palpated just beneath the clavicles while breathing. Right side scalenus muscle activation restored the movement of the right first rib. The… (More)
